Not always. From the guidelines:

> If the original title begins with a number or number + gratuitous adjective, we'd appreciate it if you'd crop it. E.g. translate "10 Ways To Do X" to "How To Do X," and "14 Amazing Ys" to "Ys." Exception: when the number is meaningful, e.g. "The 5 Platonic Solids."

> Otherwise please use the original title, unless it is misleading or linkbait; don't editorialize.

This is not quite clickbait, and perhaps not objectively misleading either, but definitely falls in the "amazing Ys" category.

I find my self amused by your comment, since on a number of occasions when I've posted the exact headline, it's been edited by moderators.
